Blends, cellulose/aramide

Fabric blends of aramid fibers and flame resistant cellulosic fibers have been described. These fabric blends are popular for use in protective garments. These blends are more comfortable than fabrics made of aramid fibers alone. " ...

Morphology evolution has been also studied in blend solutions of cellulose and aramide dissolved in dimethyl acetamide/LiCl as solvent [94,95], Selected examples are shown in Fig. 16. The initially transparent samples were kept for certain periods x at room temperature and afterwards annealed at temperatures ranging from 60 up to 130 °C until no further phase changes could be detected. 

DWI s manufacturing process relies on standard wet-laid processing. The materials are blended uniformly, and then fed into a headbox at very high dilution. The water is removed, and the web is dried. The materials are polymers selected for the application. In Titanium, the combination is chosen for alkaline resistance as well as high porosity. In Silver, polyacrylonitrile nanohbers are blended with cellulose to achieve maximum cycle life, rate capability, and minimum pore size, which also achieve advanced flame-resistant properties. In Gold, the backbone is para-aramid Twaron, which gives superior thermal stability.
